Method of forming light emitting devices comprising semiconducting single walled carbon nanotubes

A method of forming a light-emitting nanojunction comprising:

• forming a first electrode on a silicon substrate having a native oxide layer;
• depositing semiconductive light-emitting single walled carbon nanotubes (SWNTs) on a surface of the native oxide layer of the first electrode;
• growing an insulating layer on the silicon substrate, the insulating layer covering the SWNTs;
• and
• forming a second elect'rode directly on the insulating layer, the SWNTs being insulated from the first electrode and the second electrode by the insulating layer.

A method of forming a Fabry-Perrot microcavity comprising:

• forming a first Bragg reflector having alternating silicon and silicon oxide layers;
• forming a second Bragg reflector having alternating Si and SiO2 layers;
• and
• forming a nanojunction positioned between the first Bragg reflector and the second Bragg reflector, wherein the nanojunction comprises an n-doped silicon electrode, a p-doped silicon electrode, and a semiconductor insulating layer including single walled carbon nanotubes (SWNTs) positioned between the n-doped silicon electrode and the p-doped silicon electrode, wherein the SWNTs are embedded in or covered by the semiconductor insulating layer.
